| Description | Sunset Yellow FCF (Sunset yellow) is an orange azo dye with pH-dependent absorbance.Sunset Yellow FCF is used in food, cosmetics and pharmaceuticals.It is used as a colorant food additive in many food products.They may be cytotoxic and genotoxic, so care must be taken when using these materials as food additives. |
| In vitro | Sunset Yellow FCF (250 μg/ml) reduces LPS-induced and allogeneic mixed lymphocyte reaction-induced proliferation of isolated mouse splenocytes.[3] |
| In vivo | Sunset yellow FCF (0.325 mg/kg; mice) induces chromosomal aberrations in somatic and germ cells and morphological abnormalities in sperm in mice, but it is not genotoxic in a micronucleus gut assay in mice when administered at doses up to 2,000 mg/kg.[4] |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
